Code Testing
AI tools that generate unit tests, review pull requests and turn specifications into tested code, for teams who want bugs caught before they reach users.
Testing tools in this category split three ways. Some write test cases and run them. Some read a pull request and comment on it the way a reviewer would. The rest are agents that work across a whole codebase, so a change is checked against code the tool has read rather than a single file pasted into a prompt.

Too few tests, or too slow a review?
If coverage is the problem, TestSprite automates test case generation, CodiumAI focuses on unit tests, and Bito and GitHub Copilot can write tests from inside the editor. If the queue of pull requests is the bottleneck, Zencoder uses what it calls Repo Grokking to understand an entire codebase.
Start from the spec
Tessl is a spec-driven development platform that turns software specifications into tested code. The tests are only as good as the spec, so read what was generated before trusting a green run. Whatever generates your end-to-end tests, make sure they cover right-to-left pages and Arabic input if your product has them.
